MACHINE FOR THE MANUFACTURE OF PAPER TWINE.

1,241,943. Specification of Application filed June 11,

To all whom it may concern Be it known that I, ARTHUR DmooK, a subject of the King of Great Britain, residing at Stockport, in the county of Chester, England, have invented certain new and useful Improvements in Machines for the Manufacture of Paper Twine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for the manufacture of paper twine from paper ribbon (or ribbons) which is twisted into twine in a damp or wet state by suitable means and which may have incorporated in it a hemp or the like twine.

. The object of the said invention is to improve the appearance and increase the strength of such twine, to allow of the use of weaker paper than hitherto used in its manufacture, and to cheapen the means used for'the said manufacture:

.I attain this object by the machine illustrated in the accompanying drawings in Figure 1 is a side'gfew, and Fig. 2 a front machine -constructed in accordance with onfe nibodini ent :of the said invention,"Figas#ig ifiiiihtl fi are" front views of details ata'n enlargedscale, Fig. 4 being sectiona1-, and F-ig.

of notches we (see Fig. 3). In front of the bar I are removably arranged a numberof plates or blocks n each having a circular hole 0. The plates or blocks n (see Fig. 5)

may be made from pot, porcelain, metal or other suitable material and are provided with grooves so that they can he slipped onto or off their 'rods 7) at will, and there is one plate or block n for each pair of feed rollers f and g. The hole 0 .is of. suitable size to suit the width of paper ribbon a being dealt with, and a number of; interchan eable plates or blgcka n havingholes of di erentlsizes to suit the difi'erent widths of paper may be provided. In front of the platesor blocks a a niunber of grooved; ulleys g are secured toarotary shaft r. T; ere are as many pulleys'asnthereare pairs'of feed rollers f and g and ,eachpulle is vided with an annular groove 8.

miti at ng. seamstress native form of the improved machine where a slightly increased drag on the paper ribbon is of advantage or immaterial, the grooved pulleys may be dispensed with and in lieu t ereof one or more open or closed eyes 6 may be provided to keep the paper ribbon a in its folded condition until twisted. The said eyes may be of any suitable material such as pot, porcelain, metal or the like.

According to the preferred form of the improved machine, also where a slightly increased drag is of advantage or immaterial, in lieu of the said grooved pulley there its way may be provided, see Fi s. 7, 8 and 9, two guides t and a for each p ate or block n and an eye '0, the aper ribbon a passing over the guides t ans u and throu h the eye '0 on to the bobbin j. T 0 said guides and eye may be of any suitable material such as pot, porcelain, metal or the like. I preferably mount the plate or block n, the guides t, u and eye 1) on an oscillatable bracket to which may have means for readily securing it in position, so'that they can be swung out of theway when the flier, is to be removed. The eyes 1) shown in Fig. 6 may also be mounted onan oscillatable bracket as shown. I

i the combination of means I claim:

1. In a machine for making twine of the character described, the combination of an element having a cylindrical hole, means for feeding a ribbon of suitable width through said hole in such a manner as to effect the continuance of a previously started double flat fold therein, with means for twisting the folded ribbon.

2. In a machine for making twine of the character described the combination of an element having a cylindrical hole 'therein ada ted to continue a previously started dou le flat fold in the pa or ribbon as it is fed through said hole, wit means for twisting the folded ribbon.

3. A, machine for 'making paper twine comprising, in combination, means for feeding the paper ribbon means for moistening the paper ribbon as it is being fed, an element provided with a hole of suitable shape to abruptly continue at approximately the receivin end of the hole a previously starteddoubIe flat fold in the paper ribbon as it is being fed therethrough, with means for twisting the folded ribbon.

4. In a machine for making paper twine for moistening the paper ribbon, at bar having a lon 'tudinally straight surface for fnctiona y engaging the top surface of the ribbon transversely thereof, an element provided with a hole, means -for feeding ggcment'with said hole, so constructed ed around t .means for I;

said hole, so constructed an and relatively arranged t continuance of a pree flat fold in the ribbon with means for twisting as to effect the abru viously started doub as it is being fed, the folded ribbon. V

5. In a machine for the manufacture of paper twine from pa er ribbon, a bar for keeping the paper ribh on flat, said bar having a slot for centrally positioning a core down on. to the paper ribbon to the rear of the folding portion thereof, a plate in front of said bar having a hole for folding the paper ribbon around the fibrous core, a guide in front of the plate, and twisting means for twisting the paper ribbon after it leaves the guide.

6. In a machine for the manufacture of paper twine from paper ribbon, a bar secured to the frame of the machine for keeping the paper ribbon flag, a bracket oscillatably mounted on the rame of the machine in front of the bar, a plate removably secured to the bracket and having a hole for folding the paper ribbon, a guide secured ,on the bracket in front of the plate for keep-. ing the paper ribbon in a folded state, and twisting means for twisting the paper ribbon after it leaves the guide.
